Did Jack E. Robinson pay for negative mail against himself?

Over the weekend I’ve received some phone calls from confused social conservatives. They have been getting a series of “pro-equality” mailings from Jack E. Robinson touting his progressive values. At the forefront is his support for Gay Marriage. What is odd is that the pieces have most definitely been sent to signers of the Vote On Marriage petition. That data through Know Thy Neighbor is publicly available and is in some databases. Did Jack E.’s campaign staff mistake those that signed the “marriage petition” as pro-gay marriage? If so he just paid for a negative mailing campaign against himself.
